Baltimore, MD (October 30, 2007) – Under Armour, Inc. (NYSE: UA) today announced financial results for the third quarter ended September 30, 2007.

Net revenues increased 46.3% in the third quarter of 2007 to $186.9 million compared to net revenues of $127.7 million in the third quarter of 2006. Third quarter net income increased 25.4% to $20.0 million compared to $16.0 million in the same period of 2006. As previously reported, in the third quarter of 2006, the Company received a $2.3 million benefit to net income, or $0.05 per diluted share, as a result of the impact of state tax credits. Diluted earnings per share for the third quarter of 2007 was $0.40, on weighted average common shares outstanding of 50.1 million compared to $0.32 per share on weighted average common shares outstanding of 49.6 million in the third quarter of the prior year.

Driven by strong growth across Men's, Women's, and Youth, apparel net revenues rose 44.8% in the third quarter of 2007. The Compression and Training categories continued to be the main drivers of revenue growth across the apparel business, while an expanded product assortment in Golf and the launch of the Mountain product category also made healthy contributions to top line growth.

"Our third quarter results reflect strength in both our core apparel business and continued growth in new product categories," stated Kevin Plank, Chairman and CEO of Under Armour, Inc. "We're especially excited about the success of our women's marketing campaign entitled BoomBoom-TAP™, which illustrated our dedication to the Team Girl consumer. The results included 49% top line growth in our Women's business this quarter. This is further proof that the female team athlete continues to demand innovative, performance-oriented product, and we intend to fulfill that demand as we expand our product offering for this consumer.

"Our ability to tell great stories about key growth drivers is also benefiting from our improved retail presentation. With new Under Armour concept shops being installed in many of our key accounts and the upgrades we've recently made to our online consumer site, we're enhancing our brand presentation for a wide range of consumers. We are also opening our first store offering a fully-integrated Under Armour Brand experience later this week in Annapolis, Maryland."

Gross margin for the third quarter of 2007 remained steady at 50.6% compared to 50.6% in the prior year. Selling, general and administrative expenses decreased to 32.5% of net revenues in the third quarter of 2007 compared to 33.4% in the prior year. The Company had previously indicated that third quarter marketing spend would be above the range of 10% to 12% of net revenues. However, based on the growth in net revenues as well as the timing of investments in the Brand, marketing expense was 11.5% of net revenues for the third quarter of 2007. The Company still expects to invest in its marketing budget at the high-end of the range of 10% to 12% of net revenues for the full year.

Balance Sheet Highlights

Reflecting the Company's planned investment in core inventory to position itself for anticipated consumer demand, inventory totaled $151.8 million at September 30, 2007, compared to $75.0 million at the end of the same period of the prior year. Cash and cash equivalents were $14.5 million at September 30, 2007 compared to $44.3 million at the end of the same period of the prior year reflecting a planned investment in working capital and other infrastructure investments. The Company had borrowings outstanding of $10 million under its $100 million revolving credit facility.

Outlook for 2007

For 2007, the Company had previously estimated annual net revenues in the range of $580 million to $590 million and annual income from operations in the range of $79.0 million to $81.0 million. However, based on the Company's performance year-to-date, the Company is increasing its outlook for 2007.

The Company now expects annual net revenues for 2007 in the range of $590 million to $600 million, an increase of 37% to 39% over 2006, and annual income from operations in the range of $81.5 million to $83.0 million, an increase of 42% to 45% over 2006. The Company now anticipates fully diluted weighted average shares outstanding of approximately 50.0 million for 2007.

Preliminary Outlook for 2008

The Company has previously stated its long-term growth targets of 20% to 25% for the top and bottom lines. For 2008, the Company believes net revenues and income from operations will exceed the long-term growth targets of 20% to 25%. In support of certain key growth initiatives, the Company expects to increase its investment in marketing from the historical 10% to 12% of net revenues to 12% to 13% of net revenues for the full year in 2008.

Mr. Plank concluded, "As we look out to 2008 and beyond, we remain excited about the opportunities to expand the reach of the Under Armour Brand into new product categories and regional markets. And, with increased revenues, we have leverage to make a greater investment in marketing to support our launch into new large, scalable businesses. Our focus on performance and innovation has allowed us to build credibility with athletes of all sports. We are focused on achieving the next significant milestone in our story as a growth company as we execute our launch of Under Armour performance training footwear in 2008."
